MACHINE FOR HEADING CANS.'

..PCIFATN forming part of Letters Patent No. 740,599, dated etobe- 6, 196,3. Application filed November 29, 1901. Serial No. 83.969. (No model.)

To a/ZZ whom t may concern:

Be it known that I, WILLIAM H. SMYTH, a citizen of the United States, residing at Berkeley,'in the county of Alameda and State of 5 California, haveY invented certain new and useful Improvements in Machines for Heading Cans; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to a machine for assembling the heads and bodies of cans during the process of their manufacture.

'The object of the present invention is to provide asimple, cheap, and efficient machine for the stated purpose particularly adapted for use in small factories or for conditions in which a foot-power machine is desirable.

Another object is to provide means whichl will avoid the destruction in the heading process of can-bodies which have become unduly distorted prior thereto. Y

One form of the machine is illustrated in the accompanying drawings, in which-1 Figure l is a sectional elevation of the machine, showing an arrangement adapted to -the employment of foot-power. Fig. 2 is a detail, partly in section, ofy one of the canheading chucks with its presser. Fig. 3 is a detail sectional elevation of the headingchucks in position. Fig. ai is a horizontal section of Fig. 3. Fig; 5 is avertical sectional elevation through :ttc of Fig. 3. Fig. 6 is a front elevation of the machine.

As the machine consists of two sides which are alike in every particular with the' exception of slight details in the power mechanism, which will be particularly pointed out later, it will simplify the description to refer to but one side of the machine. I will therefore adopt this method, it being understood that the description hereinafter refers equally to both sides.

Referring to the drawings, A is an arm pivoted at its lower end by means of a shaft a in a suitable frame and having, preferably, a trough-form section. To its upper end are attached, preferably, two curved fingers A' A', adapted to partially embrace a can-body. a' is a stop-link limiting the independent motion between the arms A and E. Extend- 'ing outwardly from each side of the troughform armA is a cylinder B, trulyboredand concentric with the curvature of the fingers A' A. Extending into the interior of the shell of the cylinder B is a transverse slot b, and extending through the wall of the cylinder is also a pin or bolt b'. In each of these cylinders is located a solid ring or annulus D, ntting snugly therein and bored to the exterior diameter of a can. This 'ring or annulus is also slotted a short distance from one end, the slot d' corresponding to that in the cylinder B. Corresponding to the position of the slot d' is an internal annular groove or recess D', whose forward edge is tapered or sloped to the normal internal diameter of the ring,

as shown at d. Near the outer end of the ring is provided two shallow V-shape grooves d2 and cl3, and a longitudinal radial slot d4 is provided to receive the inwardly projecting end of the pin or bolt b'. The forward edge a sloping enlarged mouth or entrance d5 to the ring, as shown in Fig. 2, leaving between the slopes d5 and d a plane internal ring surface d6 of the exterior diameter of the can, or a trie larger. All this is shown particularly in Fig. 2. Secured upon the outside of ring Din a depression beneath its normalexterior surface are springs D2, their forward ends bent inward and slightly beyond the deepest portion Vof the annular groove D'. Seated within the ring D is a presser G, whose forward face when retracted is adjacent to the outer edge of the groove D', as

the periphery of the presser C is a groove c,

of the ring D is preferably beveled, forming 'Shown' in Figs. 2, 3, and i. Extending around containing a` spring-ring c', engaging with l one of the grooves d2 and di. E is anfarm secured at its lower end upon the shaft a to be oscillated thereby Aand provided with curved jaws or ingers E', whose inner curvature corresponds to'that of a canl and also as to position corresponds in distance from theA center of oscillation with the `ngers A A', as shown in Figs. l and 4. Thus the parts Ef and the fingers A' constitute the opposing jaws of a two-part segemental clamp. Upon the upper end of the arm E is a curved or arc-shape platee, as shown in Fig. l. Hinged to the presser by any suitable means (shown in the drawings as a transverse pin) is ak lever F, its opposite end loosely connected to the inner side of the frame in any suitable man- ICC ner, (indicated in the drawings as aball-andsocket connection g in the frame G.) Attached to and intermediate of the side ofthe frame G, as shown in Fig. l, is a body-rest g. A foot-lever H is secured upon the shaft et, which, as has already been stated, is journaled in the frame G. On the opposite side from H and secured upon the shaft a is a counterweighted arm I, and resting above and' intermediate of the frame G is a suitable canchute .I of any suitable form.

In operation and assuming the chute J to be filled with cans the lowermost can will be supported upon the body-rest g. `Heads having been deposited by the operator in the slots b, the treadle II will then be depressed, carrying the arm E forward, the jaw E carrying the lowermost can with it till it is embraced between and rounded up by the segmental clamp-chuck formed by the jaws E E and A A. The arm A will be retained in the position shown in Fig. l during the independent motion of the arm E to embrace the can-body by the levers F, owing to the friction of the snugly-fitting pistons or pressers D in their seats in its upper end. Further motion of the treadle will carry the arm A and its grasped can between the levers F,

' which force the pressers C inward, and by ing the heading of the can.

frictional contact of the spring-ringe the rings D,with the contained heads,which rest in front of the presser-faces. The heads are supported from displacement by the springs D2. Continued motion of the foot-lever carries the pressers till the ring D rests against the fingers A E, having passed over thev end of theY can. Still further motion of the foot-lever causes the levers to force the presser C forward in the ring D, the friction of the springring c being overcome. Thus the head is forced centrally on the cnd of the `can by the incline d., the slightly-bell-mouthed character of the ordinary can-head assisting the entrance of the body thereinto, thus complet- A slight further motion of the foot-lever carries the levers past the central point, withdrawing the ring from around the headed can. During these operationsthe plate e has passed under the bodies in the chute, preventing them from dropping downward. The first return motion of the foot-lever II, which is caused by the counterbalance I, carries the arm E backward and permits the headed can to roll out, the trough-form character of the arm A guiding the can out of the machine. Further return motion brings the arm E into engagement with the stop-link a and carries the arm A back to its original position. This has had the effect of retracting the piston C and ring D till the backward motion of the ring D is arrested by the pin or bolt b. Thus the presser C, with its friction-ring c', is carried back to its normal starting position, with the friction-ring c resting in groove cl2 and the plate e removed from beneath the can-bodies, and the machine is again ready to repeat these operations indefinitely.

By the construction heretofore described it will be seen that can-bodies which have been diametrically distorted to a greater extent than will enter the chuck are rounded up and trued in the can-body segmental clamp-chuck before being operated upon by the unbrokenring heading-chuck, so that many can-bodies which would otherwise be irretrievably ruined in the process of heading are saved and made into good cans.

It is obvious that many changes may be made in the arrangement of this device without departing from the essential nature of the invention. For example, the power arrangement and frame-mounting shown are not of the essence of this invention and are merely shown in this form as illustrating a simple character of mounting. The footlever may be displaced by any suitable continuous power mechanism, and the oscillating character of the cylinder motions may be changed to straight reciprocating motions. Feed-chutes may be supplied for the heads as well as the bodies; but all these changes and modifications being within the ordinary skill of mechanics it is not necessary that they should be more fully described or illustrated herein.

It is obvious, of course, that the means employed are adapted to effect the heading of other than cylindrical cans by merely changing the form of the chuck to correspond with the sectional form of the can. Therefore when I employ the word ring or annulus I intend it to be understood in its broadest and most generic sense as any unbroken circumscribing form of ring, such as oval,

rectangular, or polygonal forms.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
